また金属同志の当り音もない。In the above configuration, the maximum force F when starting and stopping the compressor
When the plate spring member 3 is made up of three leaf springs of different lengths, the vibration isolating rubber 11 comes into contact with the longer leaf spring in sequence, changing the spring constant and changing the rotational direction displacement. It can be suppressed to δ1 shown by the broken line 0-a-b-c in Figure 5,
There is also no sound of metal comrades hitting each other.
もし板バネ部材がないと第5図00−dの曲線で示され

くできる。As described above, the anti-vibration support device according to the present invention includes a mounting board on which at least a pair of leaf spring members constituted by a plurality of leaf springs of different lengths are erected, and a mounting board located on the board and engaged with the leaf spring members. Since it is composed of a pillar-shaped vibration isolating rubber member that is stopped, and a cap body that is attached to the upper surface of the rubber member and has a mounting rod, the vertical spring constant of the vibration isolating rubber member can be made sufficiently small. The vibration isolation effect during compressor operation can be increased.
